N. Volkow and H. Schelbert. Addiction is a lot like other diseases, such as heart disease. Both disrupt the normal, healthy functioning of the underlying organ, have serious harmful consequences, and are preventable and treatable, but if left untreated, can last a lifetime.
there is a dog from Africa called a Basenji, it doesn't bark, it sorta yodels. and also the visila from south America is said not to bark Please don't listen to all of the smart arses. Deaf dogs bark very little. But all dogs bark.

This is how you greet a dog in dog language in a non-confrontational way. stranger runs over, asserting dominance on a dog they have just met and the dog's reaction is to communicate to this being that they do not wish to be dominated. Unlike horses and deer who are flight animals, a dog is a fight animal and will communicate his displeasure with a growl and/or a snap or bite.
